Rafter Thrust Design Guide
| Roof Type | Typical Thrust (kN) | Typical Pitch (degrees) |
|---|---|---|
| Residential Low-Pitch | 5 – 20 | 10 – 25 |
| Residential Standard | 20 – 50 | 25 – 40 |
| Commercial Steep | 50 – 100 | 40 – 50 |
| Industrial Heavy | 100 – 200 | 20 – 40 |
📌 Note: Results are based on simplified structural analysis. Horizontal thrust = (Total Load × Span) / (2 × tan(pitch angle)). Tie force equals horizontal thrust to prevent rafter spreading. Safe thrust includes safety factor for design loads. Actual structural design must consider rafter size, material properties, connection details, wind loads, seismic loads, and comply with local building codes (IBC, Eurocode, etc.). Always consult a licensed structural engineer for final design verification.
